CAR-DOOR BRACKET.

Original application filed March 24, 1913, Serial No. 756,425;

Specification of Letters Patent.

18, 1913. Serial No. 790,412'.

To all whom t may concern Be it known that I, FRED Marrrnws, a citizen of the United States, residing` at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Car-Door Brackets, of which the following is a specification.

My invention relates to a bracket for supporting and also guiding and retaining the lower edge of a sliding door, for example, an outside sliding door of a railway box car; and the invention has for its object the provision of a bracket of the above type which, while supporting the door so that theusual hangers and track at the upper edge o-f the door may be dispensed with will enable the car door to be easily moved vback and forth across the door opening, which can be applied to the outside of the car without danger of having its operation hindered by the lodging of dirt, ice or other material in the bracket, which will give a maximum degree of strength and durability, and which will be inexpensive to manufacture.

The invention contemplates providing the bracket with a roller on which the lower edge of the door bears, the roller being arranged so that it cannot be removed from the bracket when the door is in its open position.

The invention has for further objects the arrangement, construction and combination of parts hereinafter more fully described and claimed.

The preferred embodiment of the invention is illustrated in the accompanying` drawing, in which similar characters of reference designate corresponding parts, and in whicl Figure l is a fragmentary view, in elevation, of the front lower corner of a car door showing the arrangement of one of my improved supporting brackets. Fig. 2

. is a cross-sectional view taken through the lower edge of the door showing the bracket in elevation. Fig. 3 is a view, in elevation, of the bracket taken from the inside. Fig. et is a plan view of the supporting bracket. Fig. 5 is a side elevation of the same. Fig. G is a sect-ion taken on line G-G of Fig. 5.

Referring to the'drawing, A designates the side wall of a box car formed with the usual opening B and closed by a sliding door C, which is supported on my improved bracket.

lThe supporting bracket, as a whole, is designated by D and is provided with an attaching plate Ewhich is secar-ed to the side sheathing F and to the nailing strip F fitted inthe Z-shaped side sill G.

The particular construction of the car body is obviously of no importance as it would require but little skill to apply the Y and terminates in an upwardly extending guide lip J. The guide lip is not intended to normally engage the lower edge of the door but is to prevent the door from swinging outward and off the bracket when the car weaves. In order to withstand the continuo-us striking of the door against the upstanding lip I preferably form it with a curvature which makes it very strong. Should it be desirable to open the car door when it is engaged with the lip, as for example when the track on which the car stands is elevated on one side, the door being only engaged with the middle of the lip, minimizes the friction when opening the door. The roller L ts within the aperture I and is formed with studs M, one of which bears in a circular socket N in the outer or lip portion of the bracket, and the other in a groove O formed in the attaching plate E of the bracket. The roller is retained in the bracket by means of a lug P formed at one edge of the groove O which is bent down over the stud that bears in this groove, after the roller has been put in place, as is best shown in Fig. 8. The brackets are secured to the car by any suitable means. I have shown bolts Q, extending through bolt holes in the bracket and through the side sill of the car, and also a lag screw R for each bracket which is screwed into the nailing strip F before the bracket is put in place, the attaching plate E of the bracket being formed with a slot S and on the front side with a hood 'l Which incloses the head of the lag scren7 and prevents the removal of the bracket when the door is closed. The bracket is further strengthened by a rib U apertured to make room for the roller and extending from the hood T to a point near the upper edge of the web H. rllhe edges of the aperture l and the upper edge of the rib U are preferably spaced a short distance away from the roller L so as to prevent dirt, ice or other material from lodging in the bracket and impeding the movement of the roller.

This application is a division of my copending application Serial No. 756,425, filed March 2li, 1913.

l do not claim herein the door organization as a Whole, this application being limit ed to the construction of the bracket per se.

Vhile I have described my invention in its preferred embodiment, it will be understood that modifications might be made without departure from my invention. Therefore, I do not Wish to limit the invention to the particular construction shown and described except so far as limited by the claims herein.

What I claim is:

l. A car door bracket comprising an attaching plate formed With a vertical slot and a hood for the slot, a lip connected with said plate With a horizontal web provided With an aperture, a roller adapted to be in serted in said aperture and formed at opposite ends with studs, said lip being formed with a curvature and on its inside with a recess to receive the stud on one end of the roller, the attaching plate being formed With a groove in Which the other stud bears, and a lug on the attaching plate adapted to be bent down so as to close the upper end of the groove7 after the roller has been put in place.

Q. A car door bracket comprising an attaching plate formed With a vertical Web., a horizontal Web, and a lip projecting upwardly from said horizontal web, said horizontal and vertical Webs being formed with apertures, and a roller revolubly mounted in said apertures.

3. A car door bracket comprising an attaching plate formed with a slot and a hood over said slot7 a vertical web extending outivardly from said hood7 a horizontal Web projecting from the attaching plate above said vertical Web formed with an upstanding lip7 said horizontal and vertical Webs being formed with apertures and said attaching plate and forward part of the bracket with sockets, and a roller arranged in said apertures having studs which bear in said sockets.
